The air inside the balloon is at a higher pressure than atmospheric pressure so the gas molecules inside the balloon are closer together on average than gas molecules outside the balloon. This means that the repulsive forces between the gas molecules inside the balloon are greater than the repulsive forces between the gas molecules outside it. When the balloon is opened, the gas molecules in the open end at the border between the higher pressure interior and lower pressure exterior will experience a greater repulsive force from the gas molecules inside the balloon than the molecules on the outside. This means that they experience a net force pushing them out of the balloon. As these gas molecules are pushed out by the gas inside the balloon, they push back on it with an equal and opposite force (due to Newton's 3rd Law of Motion). This equal and opposite reaction force causes the gas in the balloon to be pushed in the opposite direction to the escaping gas, which in turn pushes the balloon. As more and more gas escapes, the reaction force on the balloon continues to accelerate it, making it shoot off, until enough gas has escaped for the pressure inside the balloon to have dropped to the same level as the pressure outside the balloon.
What else can I help you with?
What will happen to the water level in a straw when the balloon is filled with tap water and then squeezed?
When the balloon is filled with water, it creates pressure on the water inside the straw, causing the water level in the straw to rise. When the balloon is squeezed, the pressure is increased, causing the water level in the straw to rise even further due to the increased force.
A thi rubber ball shaped container of gas?
A self-sealing rubber balloon filled with gas can be compressed when squeezed. The gas molecules inside the balloon move closer together, increasing the pressure of the gas. The balloon reverts to its original shape when the pressure is released.
What is the difference between a water balloon and a normal balloon?
A water balloon is filled with water, and other balloons are filled with air or helium.
What is the density of balloon?
Density of any balloon depends on the material of the balloon and how much the balloon is filled.
Which of a hydrogen filled balloon air filled balloon and a carbon dioxide filled balloon will deflate the fastest and which is the slowest and explain your answer?
A hydrogen balloon will deflate the fastest because molecules of hydrogen are the smallest and thus will more easily slip through the latex of the balloon. The carbon dioxide-filled balloon will deflate the slowest because these molecules are the biggest, and thus will have more trouble escaping the tiny pores in the balloon.
What happens when you add heat to a balloon filled with air?
The balloon expands.
What is placed inside the balloon that form its shape?
The balloon is filled with a gas.
How far can a water balloon be toss before it breaks?
I think a water balloon can be tossed if the water balloon is filled lightly. If the water balloon is filled heavily it might break before someone catches it. Also I did this before and I measured it and it was 74 feet and 5 inches exactly!
Why does a balloon filled with helium rise with a balloon filled with an equal volume of average atmospheric air does not?
Helium is less dense than air, so a balloon filled with helium is lighter than the same volume of air. This buoyancy force allows the helium-filled balloon to rise. On the other hand, a balloon filled with air has the same density as the surrounding air, so there is no buoyant force to make it rise.
Which balloon can deflate faster?
A balloon filled with helium will likely deflate faster than a balloon filled with air because helium molecules are smaller and can escape through the balloon material more easily.
What are balloon animals filled with?
air
What would you exect to happen to a balloon filled with air was put into a refigerator?
Putting an air-filled balloon in a refrigerator will cause it to shrink.
